5. Kassius Ohno

When The Shield debuted, Roman Reigns was somewhat of a wildcard, a guy who even hardcore fans didn't know a ton about.

While Reigns has more than delivered so far, there was a lot of initial talk that he should have been replaced in The Shield.

His replacement? Kassius Ohno.

The reasoning for this was that, like Dean Ambrose and Seth Rollins, Ohno made quite the name for himself on the independent scene. Thus, debuting the three together would make sense because of their supposed indy connections.

Of course, there's also the belief by many that Ohno is ready for the main roster, and The Shield would have been a great way to get him there.

While Reigns ultimately turned out to be the third member of the group, that doesn't mean that Ohno won't become the fourth.

After all, he may now be the most talented and polished superstar down in NXT.

This week's Raw ended with a major surprise: The debut of Big E Langston.

In the middle of the show's main event, Langston walked down to the ring alongside AJ Lee and then destroyed John Cena with his finisher. This shocking twist has now opened up all kinds of possibilities.

There are, quite literally, countless scenarios that could play out now that involve Langston, AJ, Cena, Dolph Ziggler, Vickie Guerrero and others.

But one scenario that we naturally have to mention is that Langston is actually the fourth member of The Shield.

Yeah, Langston didn't debut with the same attire that The Shield did, and he could simply be working for AJ, Vickie or even Ziggler. But to be honest, anything seems possible when it comes to the WWE.

Langston could indeed be working for The Shield somehow someway, and it may ultimately be revealed that he is the fourth member of the group.

After all, every member of The Shield is an NXT stud, and Langston is one, too.

He may not look like a natural fit in the group, but the fact that he debuted not long after them certainly makes it possible that he's a part of it.
